The Israeli security bulletin came in the midst of heated rhetoric on the part of the U.S., Iranian and Israeli political religious and military leadership and follows the recent assassination of a key scientist in Iran's nuclear enrichment program. If the rhetoric is to be believed, there is a deep concern that Israel might launch a military strike against Iran during the spring of 2012.
The intelligence community assessment of that possibility, based on interviews conducted by ABC News, is considerably more nuanced, taking into account as it does the political will of the United States during an election year, the fragile nature of Great Britain's coalition government , the willingness of other allies to join in an offensive, the roles of Russia and China and Saudi Arabia in such a confrontation, and whether Israel would really be willing to launch a unilateral strike.
"But in this situation, the political rhetoric is actually quite important," one official told ABC News. "And that is why the official position -- of the U.S, England, France, Canada, Israel and allies -- is that nothing is off the table."
An apparent shift in the Israeli/U.S. relationship has complicated matters, however, said the official. In the past, Israel would probably have given the U.S. a heads up were it to launch a strike. Now that might not be the case. Among the English-speaking allies of the U.S., say multiple intelligence officials, there is currently a very limited expectation of any early warning.
While much of the public attention has focused on Israel and the rifts within its leadership on how to respond to Iran's nuclear weapons program, the reality for Iran's leadership is also problematic. After threatening to strangle the world oil supply through the straits of Hormuz, Iran "has boxed itself into a corner," said one Western intelligence official. "It would be quite humiliating for them to back down."
The Israeli security letter sums up the resultant risks very clearly.
"In conclusion, we operate according to the information that Iran and Hezbollah are working hard and with great intensity to release a 'quality' attack against Israeli/Jewish sites around the world."
